BY QM and United States Patent FOLDING CAMP CHAIR Alexander Csorgo, Romulus, Mich. Application October 5, 1955, Serial No. 538,614

1 Claim. (Cl. 155-147) The present invention relates to new and useful improvements in camp chairs and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character which, when it is not in use, may be compactly folded with a minimum of effort.

Another very important object of the invention is to provide a folding camp chair of the aforementioned character comprising novel means for pivotally connecting the back and the front legs to the seat.

Still another important object of the invention is to provide a folding camp chair of the character described which is principally of metal construction.

Other objects of the invention are to provide a folding camp chair of the character set forth which will be comparatively simple in construction, strong, durable, of light weight, attractive in appearance, comfortable and which may be manufactured at low cost.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part thereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a perspective view of a folding camp chair constructed in accordance with the present invention;

Figure 2 is a bottom plan view of the chair with a portion broken away;

Figure 3 is a fragmentary view in vertical section, taken substantially on the line 3-3 of Figure 1;

Figure 4 is a vertical sectional view through the chair, taken substantially on the line 44 of Figure 1;

Figure 5 is a view in side elevation, showing the chair folded;

Figure 6 is a fragmentary view in vertical section through the pivotally connected intermediate portions of the legs;

Figure 7 is a perspective view of showing the parts separated; and

Figure 8 is a view in horizontal section, taken substantially on the line 8-8 of Figure 1.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a seat 10 of suitable material, preferably plywood, which seat may be of any desired dimensions.

Mounted on the rear marginal side portions of the seat 10 is a pair of hinges which are designated generally by reference character 11.

The hinge assemblies 11 comprise inverted angle members 12 which are apertured to accommodate screws 13 for securing said members longitudinally beneath the side portions of the seat 10. Secured by rivets 14 on the depending fianges or legs 15 of the angle members 12 and the hinge assembly,

2,779,394 Patented Jan. 29, 1957 the longitudinal edges of the seat 10. Longitudinally elongated housings 17 are secured by relatively long and short rivets 18 and 19, respectively, on the upper portions of the plates 16 and overlie the seat 10. The housings 17 are formed from a single length of metal bent upon itself at an intermediate point and formed to provide face abutting end portions or legs 20 (see Figure 8) which are apertured to accommodate the rivets 19. The relatively long rivets 18 traverse the forward end portions of the housings 17. The bight portions 21 of the housings 17 are notched or recessed, as indicated at 22.

Mounted for swinging movement in a vertical plane on the rear portion of the seat 10 is a back which is designated generally by reference character 23. The back 23 comprises a panel 24 of suitable metal which is mounted on the upper or bight portion of a substantially inverted U-shaped support 25, said support including divergent leg portions 26 which are journaled on the rivets 18 in the housings 17. When the back 23 is in raised or operative position, the legs 26 rest against the rear end walls of the housings 17. When the back 23 is in folded or inoperative position, the legs 26 of the support 25 rest in the notches or recesses 22 in the bight portions 21 of the housings 17.

Mounted for swinging movement beneath the seat 10 is a pair of front legs 27. The legs 27 comprise divergent intermediate portions 28 which terminate in parallel lower end portions 29. The upper ends of the legs 27 are affixed in any suitable manner to a tubular crosshead 30 which is journaled between the rear end. portions of the flanges or legs 15 of the angle members 12. Thus, the legs 27 are pivotally mounted for vertical swinging movement beneath the seat 10.

Pivotally mounted at an intermediate point between the legs 27 is a single back leg 31. An elongated rivet or pin 32 (see Figure 6) pivotally mounts the leg 31 on the legs 27. Washers 33 are mounted on the pin 32 between the legs 27 and 31. Mounted on one end of the leg 31 is a crosshead 34 which is engageable in a book 35 provided therefor beneath the front portion of the seat 10 for releasably securing said leg 31 in open or operative position. On the other end of the leg 31 is a substantially similar crosshead constituting a ground engaging foot 36.

It is thought that the use of the chair will be readily apparent from a consideration of the foregoing. Briefly, with the chair in folded position as seen. in Figure 5 of the drawings, the seat 10 rests on the collapsed legs 27 and 31 and the back 23 rests on said seat, the notches or recesses 21 accommodating the legs 26 of the support 25. To unfold the chair for use, the back 23 is swung upwardly and rearwardly until arrested by the engagement of the legs 26 of the support 25 with the rear Walls of the substantially oval housings 17. The legs: 27 and 31 are then opened and the crosshead 34 is engaged in the anchoring or retaining hook 35 beneath the seat 10.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

A folding chair comprising a seat, hinges on the rear portion of said seat, said hinges including anglemembers mounted beneath the marginal side portions of the seat and including depending flanges, plates mountedvertically on the outer sides of said flanges and rising therefrom above the seat, a back for the seat pivotally mounted on the upper portions of said plates, a pair of spaced front legs including on one end a tubular crosshead in end abutting engagement with the inner sides of the flanges and journaled thereon, a back leg pivotally mounted at an intermediate point between said front legs, and coacting means on said back leg and the seat for releasably securing all of the legs in unfolded position beneath said seat.
